Project description:MicroRNAs (miRNAs) present in tissues and biofluids are emerging as sensitive and specific safety biomarkers. MiRNAs have not been thoroughly described in M. fascicularis, an animal model used in pharmaceutical industry especially in drug safety evaluation. Here we investigated the miRNAs in M. fascicularis. For Macaca mulatta, a closely related species of M.fascicularis, 619 stem-loop precursor miRNAs (pre-miRNAs) and 914 mature miRNAs are available in miRBase version 21. Using M. mulatta miRNAs as a reference list and homology search tools, we identified 604 pre-miRNAs and 913 mature miRNAs in the genome of M.fascicularis. In order to validate the miRNAs identified by homology search we attempted to sequence miRNAs expressed in kidney cortex from M. fascicularis. MiRNAs expressed in kidney cortex may indeed be released in urine upon kidney cortex damage and be potentially used to monitor drug induced kidney injury. Hence small RNA sequencing libraries were prepared using kidney cortex tissues obtained from three naive M. fascicularis and sequenced. Analysis of sequencing data indicated that 432 out of 913 mature miRNAs were expressed in kidney cortex tissues. Assigning these 432 miRNAs to pre-miRNAs revealed that 273 were expressed from both the -5p and -3p arms of 150 pre-miRNAs and 159 miRNAs expressed from either the -5p or -3p arm of 176 pre-miRNAs. Mapping sequencing reads to pre-miRNAs also facilitated the detection of twenty-two new miRNAs. To substantiate miRNAs identified by small RNA sequencing, 313 miRNAs were examined by RT-qPCR. Expression of 262 miRNAs in kidney cortex tissues ware confirmed by TaqMan microRNA RT-qPCR assays. Analysis of kidney cortex miRNA targeted genes suggested that they play important role in kidney development and function. Data presented in this study may serve as a valuable resource to assess the renal safety biomarker potential of miRNAs in Cynomolgus monkeys.
Project description:RNA samples from brain, cerebellum, liver, and testis of 3-year-old make Macaca fascicularis was hybridized to the M.fascicularis GeneChip, which was designed by the Laboratory of Genetic Resources, National Institute of Biomedical Innovation. Keywords: Control study
Project description:We sutured the left eyelid of one-month-old Macaca Fascicularis. Three months later, their LGN tissues were captured and mRNA sequencing was carried out to study the effect of monocular deprivation on gene expression in Macaca Fascicularis.
Project description:Macaca fascicularis (long-tailed, cynomolgus, or crab-eating macaque) is a highly advantageous model in which to study human cochlea with regard to both evolutionary proximity and physiological similarity of the auditory system. To better understand the properties of primate cochlear function, we analyzed the genes predominantly expressed in M. fascicularis cochlea.
Project description:In order to develop new safe and potent therapeutics, insights into the mechanisms underlying diabetes mellitus are urgently needed. We used proteomics profiling of the liver tissue from Macaca fascicularis with spontaneously occurred diabetes mellitus at their middle age and including two groups of the monkeys fed with the same food and high-fat and high-sugar diet for comparison.We hoped to find something new for diabetes mellitus treatment.
